HAI-1 Protein, Human, Recombinant (His Tag)

纯度:> 96 % as determined by SDS-PAGE

内毒素：< 1.0 EU per μg of the protein as determined by the LAL method

生物活性：Measured by its ability to inhibit trypsin cleavage of a fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2 (R&D Systems, Catalog # ES002). IC50 value is < 2nM .

蛋白构建：A DNA sequence encoding the human SPINT1 isoform 2 (O43278-2) (Met 1-Val 433) was fused with a polyhistidine tag at the C-terminus.

Uniprot No.：O43278-2

表达宿主：HEK293 Cells

种属：Human

预测 N 端：Gly 36

分子量：The recombinant human SPINT1 consists of 409 amino acids and predictes a molecular mass of 45.8 kDa. In SDS-PAGE under reducing conditions, rh SPINT1 migrates as an approximately 55 kDa band due to glycosylation.

缓冲液：Lyophilized from sterile PBS, pH 7.4.

Please contact us for any concerns or special requirements.

Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.

Please refer to the specific buffer information in the hard copy of CoA.

运输方式：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.

Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

稳定性 & 储存条件：Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃

Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

复溶：A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
